In accompanying drawing, which ble having a central aperture through which the 45 trates a preferred embodiment of my invention, P of an 011 can nozzle y be m serted to 1 a of a wa tresses a: printer ulle and its sup orting arm; e p g 2 is a vergical, Sectional View approxi ball race 8 where they revolve with it and premately on the line Fig and vent any substantial escape of oil from the bear- 50 Fig. 3 is a sectional plan View on the line 3 3 ing. It will be observed that the oil hole l2 1. opens into the bearing chamber at a point be- The construction shown in the drawing comtween the washers. Obviously this provision for prises a supporting arm 2 provided at its upper supplying oil to the bearing can be replaced by end with a head 3 designed to fit into the socket a grease cup mounted in the end of the arbor 5 As is well understood by those familiar with textile machinery, it is "customary to arrange the spindles of spinning and twister frames in two or more parallel rows extending longitudiof a holder of a tape tensioning device, such as that shown in my pending application Ser. No. 128,062, filed February 2'7, 1937. At its lower end this arm is provided with a circular diskin place of the thimble [3, in which event the felt packing will not be used.
It is customary to provide a fork on each side of the pulley or drum for the purpose of catching the tape in the event that it runs oil the pulley, due to misalignment or for any other reason. One fork is fastened to or made integral with the pulley supporting arm, While the other is formed at the end'of a yoke running from the support-' ing arm around the pulley to the opposite side. This construction is obj ectionable both because it afiords a place for fly tov accumulate, and also for the reason that it adds materially to the weight which must be counter-balanced. It is one of the objects of this invention to avoid these difilculties and to eliminate the'yoke. To this end the arm 2 is provided with an extension or tip I5, preferably integral with the arm, and inclined outwardly away from the drum 1, as best shown in Fig. 3. is provided at the opposite side ofthe drum and preferably .is made integral with a disk-like collar 11, similar to the part 4, and secured rigidly to the left-hand end of the arbor 5, Fig. 2, by means of a set screwl8. Thus the two elements l5 and I6 cooperate to form a tape catching fork, and the collars .4 and Il cooperate with them, respectively, to provide angular pockets in which the tape lodges inthe event that it slip oil" in one directionor another.
It will be evident from the foregoing that the invention provides a tape tensioning pulley of exceptionally simple construction, of light weight, and so organized that it can be manufactured very economically. The anti-friction mounting of thedrum and the provision for lubrication of the bearing make the device economical of power and the nature or the organization is such that relatively little area exposed for the accumulation of fly. In this connection it should be noted that the collars 4 and Il substantially fill the annular cavities or spaces in the drum adjacent to its hub and. act as shields or guards to protect the bearing from fly and dirt. It will be observed that the drum has annular shoulders closely encircling the peripheries of said'collars or hub members l and I1. Preferably the collar I! is provided with a depending lip 20 designed to catch any oil which may be carelessly left on the end of the arbor during the oiling operation and guiding such excess to a tip projecting downwardly beyond the adjacent surfaces of the collar. This tip also is spaced axially outward far enough to cause any drip from it to. fall clear of the drum, even though the drum may be tipped in a clockwise direction, Fig, 2, into an angle considerably ofi the vertical.
A corresponding member It In manufacturing the device the drum usually is assembled on the arbor with its ball bearing, and this assembly subsequently is handled I as a unit, the only additional assembling operation being to mount the arbor in the arm 2 and to. secure the collar ll on the arbor.
While I have herein shown and described a. preferred embodiment of my invention, it will be understood that the invention is susceptible of v embodiment in other forms without' departing from the spirit or scope thereon Having thus described my invention, what I desire to claim a's'new is:
1. A tape tensioning pulley structure for spin-' I ning frames and the like, comprising a supporting arm, an arbor supported at one end by said arm, a drum mounted on said arbor for rotation, a collar secured on said arbor at the end thereof opposite said arm, and members at opposite sides of said drum rigid with said arm and said collar, respectively, for catching the tape if it runs oifsaiddrum, each of said members having its free end located on the same side of the drum as the collar and arm with which itis rigid.
2. A tape tensioning pulley structure for spinning frames and the like, comprising a supporting arm, an arbor supported at one end by said arm, a drum mounted on said arbor for rotation, a collar secured on said arbor at the. end thereof opposite said arm, said arm and said collar being provided with integral extensions for catching the tape if it runs off the. drum, each of said extensions having its free end located on the same side of the drum as the col-. lar and arm with which it is integral. g
3. A tape tensioning pulley structure for spinning frames and the like, comprising a supporting arm, an arbor supported at one end by said arm, a drum, ball bearings supporting said drum on said arbor and positioning the drum both radially and axially inthe structure, and a collar secured on said arbor at the end thereof oppo- I site said arm, said arm and collar being provided with integral extensions for catching the tape if it runs 01f the drum, each of said extensions having its free end located on the same side of the drum as the collar and arm with which it isintegral, said collar andsaid arm having parts at opposite sides of said bearings extending radially beyond the bearing and c0.-'
operating with adjacent surfaces of the drum to substantially enclose said bearings andthe hub portion of the drum.
